VAPOR-STOVE.

SPECIFICATION forming part of Letters Patent No. 408,079, dated JuIyBO, 18899.

Application filed October 21, 1886. Serial No. 216,916. (No model.)

To cbZZ whom, it hwy concern:

Be it known that. I, JONATHAN S. BUTLER, a citizen of the United States, residing at Springfield, in the county of Sangamon and State ,of Illinois, have invented a new and useful Improvement in VaponStoves, of which the following is a specification.

My invention relates to vapor-stoves; and it consists in the construction and combina tion of parts, as hereinafter set forth.

In the annexed drawings, illustrating the invention, Figure 1 is a perspective view of a vapor-stove embodying my improvements. Fig. 2 is a vertical section of the oil-tank.

The numeral 1 designates the frame of the vapor-stove, which may be of any suitable or well-known construction. To the lower part of this stove-frame is permanently secured, in any suitable manner,a tank 2, which is preferably double or formed with two chambers, one within the other, theinner chamber being intended as an oil-tank, while the outer or surrounding chamber 4 is for the purpose of holding water to keep cool the oil in the inside tank in order to prevent vaporization of the oil in said inner tank. There is of course no communication between the tanks or chambers 3 and 4, and the outside one can be dispensed with, if preferred.

The oil-tank is entirely closed, except at one end, where it is provided with a short horizontally-projecting pipe 5, in which is fitted a rotatable elbow or turn-down joint (3 on the lower end of a straight pipe 7, which communicates at its other end with a watertank 8, that is supported by said pipe.

The water-tank 8 is for the purpose of receivin g water,which, by passing down through the pipe 7 and beneath the oil in the tank or chamber 3, will force or float the oil upward to the burner or burners. The pipe 7 may be secured in a vertical position, with the watertank elevated above the stove, by means of any suitable lock 9.

When it is desired to empty the oiltank, it can be done by releasing or unlocking the pipe 7 and turning it down, thus permitting the oil to flow out through the pipe 7 and tank 8 into any suitable vessel placed to re ceive it. By raising the pipe 7 to a vertical position the oil-tank can be supplied with oil through the elevated tank 8, and when it is desired to feed the oil to the burners the tank 8 will be filled with water to flow down through the pipe 7 and float the oil upward to the burners. The oil-tank has projecting therefrom a vertical feed-pipe 16, leading into a horizontal feed-pipe 17, which may be provided with a needle-valve 18, as usual.

Upon and communicating with the horizontal feed-pipe 17 is located a central vaporgenerating burner 19, which communicates with burners at each end of the stove, as usual. To the upper end of the vapor-generating burner 19, in position to be sufficiently exposed to the heat, is attached a gas-pipe 20, which extends outward and upward to burners 21, where the vapor may be ignited for the purpose of giving light when the stove is in use. The gas-pipe 20 is provided with a cock 22 of any suitable construction.

For the purpose of providing a light when the stove burners are not in operation, a pipe 23 is connected with the oil-tank, preferably through the horizontal feed-pipe 17, whereby the oil itself can be forced up to the burners 24.

In generating gas for illuminating purposes while the stove-burner is in operatiomthe pipe 20, where the heat strikes it, should be very small and only sufficient oil be let into it to supply the gas needed.

For convenience in igniting matches a roughened surface 25 is provided on a portion of the stove-top.

This apparatus can be adapted either for heating or cooking purposes by providing a heating-drum of any well-known construction when a heater is required, and in this case, if desired, the form of the oil-tank may be modified to suit the shape of the heater.

For the purpose of ascertaining when the supply of oil in the tank is getting low the tank may be provided with a water-glass 26, with a float 27 in it loaded heavy enough for the float to sink through the oil and rest on the water underneath, with a pointer on the float projecting above the water.

What I claim my invention is- A vapor-stove comprising a frame 1, supporting a top plate, an oil-containing tank secured to the lower part of said frame below said top plate and having a pipe 5 proj eating horizontally from one end, vaporburners communicating with said oil-tank, a rotatable joint 6, fitted in the outer end of the horizontally-projecting pipe 5, a pipe 7, communicating with and supported on said rotatable joint 6, and a water-containing tank 8, mounted on IO and communicating With the pipe 7 for supplying Water to the oil-tank to float the oil therein to the burners, substantially as shown and described.

In testimony whereof I have afliXed my signature in presence of two Witnesses.
